METHOD AND MEANS FOR SEALING.

Application filed 311116.12,

To all whom it may concern:

Be it known that I, WINFRED M. Bnoons, a citizen of the United States, and a resident of South Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Methods and Means for Sealing, of which the following is a specification.

This invention relates to a method and means for sealing.

In the art of sealing, as heretobefore practiced, it has been customary to mold or cast individual seals of compressible material having one or more openings for the reception of an element to be sealed such as a cord of metallic or fibrous material and then to seal such element by compressing the seal.

It will be understood that the casting or molding of a great number of individual seals necessarily is a tedious and expensive process requiring a considerable number of employees, and it is the main object and feature of this invention to obviate the necessity of molding individual sealsthereby reducing the cost of manufacture to a considerable extent.

The invention can best be understood in connection with the accompanying drawings, in which:

Figs. 1 to 5 inclusive are more'or' less diagrammatic views showing the bar from which the seals are produced and illustrating the process of producing the seal;

Fig. 6 is a view in side elevation with parts broken away and in section of an instrumentality for carrying on the sealing process.

Fig. 7 is a horizontal sectional view on the plane of line 77 of Fig. 6.

Fig. 8 is a vertical sectional view on the plane of the irregular line 8- 8 of Fig.6.

Fig. 9 is a view substantiallylike the right hand end of Fig. 7 but showing theparts in a different position. r

1 indicates a bar of compressible material such as lead which is provided with openings 2. This bar may be produced in various ways such as by casting it in plain form as shown in Fig. 1 after which openings 2 may be drilled or otherwise produced in it, but preferably the bar shown in Fig. 2 is cast with the openings initially formed in it. In the preferred form these openings are transversely extending and run all the way through the material. Into the outermost opening, as shown in Fig. is in- 123. Serial No. 644,829.

troduced an element to be sealed such as cord 8. Then as shown inFig. 5 a seal length 4, containing the element. to be sealed is sheared off the end of the bar and. compressed as shown. Openings 2.are so spaced that at least one opening is contained in each seal length.

Any suitable instrumentality may be used for carrying out the above process, but preferably in adapting the process to practical from end 8 ormember 5 mayhave a lever 9 pivoted at 10 acting as a cover. Carried vmechanical means the step of feeding the at the forward end ofv handle member 5 is an anvil 11 having a shearing edge 12' above the plane of the anvil. Adjacent this shear- .ing edge is a guide 13. through which the bar is fed so as to bring its leading end in position above the plane of the anvil. 14 a sequently the shearing and punching member will'descend, will shear the end off the bar and thereafter compress it. A spring 18 tends to keep handle members 5 and 6 separated. 7 Any suitable means maybe usedto'feed the bar forward. Ashere shown 19 is a reciprocatory member sliding in guide 20. of handle 5. Mounted on this reciprocatory member is an oscillatory mem- -ber 21 pivotally supported at 22 and having a finger 23 that extends .into one of the 26- on handle 5 and engaging pin 27 on then oscillatory member is used to manipulate the feeding device. It will be understood that by pressing the underside of the lower arm of the bell crank the reciprocatory member will be moved forward against the tension of spring 24: and that finger 23 being in one of the openings will move the bar forward one step. When pressure on the bell crank is released spring 24 will move the reciprocatory member back, but in order to do so the oscillatory member will swing on its pivot 22 as indicated in Fig. 8 and will swing in again when it comes opposite to the next opening.

The operation is as follows:

A bar is placed within member 5 and is advanced until its leading end projects above the anvil. The element to be sealed is now introduced into the exposed opening of the bar. Handles 5 and 6 are then compressed thereby shearing off the end of the bar and the seal length thus produced is then compressed.

The bar with the openings is not claimed in this application but forms the subject matter of application Ser. No. 644,836, filed June 12, 1923.

I claim:

1. The method of producing seals which consists in providing a bar of compressible material with openings, then introducing an element to be sealed into one of said openings, then severing a seal length, containing the element to be sealed, from the bar and then compressing the seal.

2. The method of producing seals which consists in providing a bar of compressible material with transverse openings, then introducing an element to be sealed into one of said openings, then severing a seal length, containing the element to be sealed, from the bar, and then compressing the seal.

3. The method of producing seals which consists in providing a bar of compressible material with openings extending clear through the compressible material, then introducing an element to be sealed into one of said openings, then severing a seal length, containing the element to be sealed, from the bar, and then compressing the seal.

a. The method of producing seals which consists in providing a bar of compressible material with transverse openings extending through the material from side to side, then introducing an element to be sealed into one of said openings, then severing a seal length, containing the element to be sealed, from the bar, and then compressing the seal.

5. The method of producing seals which consists in introducing an element to be sealed into an opening of a bar of compres sible material, then severing a seal length, containing the element to be sealed, from the bar, and then compressing the seal.

6. The method of producing seals which consists in providing a bar of compressible material with openings, feeding said bar forward step by step, introducing an element to be sealed into one of said openings between the feeding steps, severing a seal length, containing the element to be sealed, from said bar after each step, and then compressing the seal.

7. The method of producing seals which consists in providing a bar of compressible material with transverse openings, feeding said bar forward step by step, introducing an element to be sealed into one of said openings, between the feeding steps, severing a seal length, containing the element to be sealed, from said bar after each step, and then compressing the seal.

8. The method of producing seals which consists in providing a bar of compressible material with openings extending clear through the compressible material, introducing an element to be sealed into one of said openings between the feeding steps, severing a seal length, containing the element to be sealed, from said bar after each step, and then compressing the seal.

9. The method of producing seals which consists in providing a bar of compressible material with transverse openings extending through the material from side to side, feeding said bar forward step by step, introducing an element to be sealed into one of said openings between the feeding steps, severing a seal length, containing the element to be sealed, from said bar after each step, and then compressing the seal.

10. The method of producing seals which consists in feeding a bar of compressible ma terial having openings forward step by step, introducing an element to be sealed into one of said openings, then severing a seal length, containing the element to be sealed, from the bar, and then compressing the seal.

11. A cutting and sealing press comprising: an anvil, a shearing edge in a plane above the anvil, means for feeding a bar of compressible material over the shearing edge so that its leading end comes into position above the anvil and in spaced relation thereto, and a shearing member and punch moving substantially at right angles to the feeding movement of the bar to shear off the leading end of said bar into a seal length and to compress said seal length against the anvil.

12. A cutting and sealing press comprising: a pair of handle members pivotally connected and one of which is hollow to afford space for a bar of compressible material. an anvil carried at the operative end of the hollow member, a shearing member and a punch to cooperate with the anvil, and means for actuating the shearing member and punch by bringing the handles together.

13. A cutting and sealing press comprising: a pair of handle members pivotally connected and one of which is hollow to afford space for a bar of compressible material, an anvil carried at the operative end of the hollow member, a shearing member and a punch to cooperate with the anvil, means for actuating the shearing member and punch by bringing the handlestogether and means independent of the closing movement of the handles for feeding the bar through the hollow member.

14. In a sealing press, a hollow member to receive a bar of compressible material having openings, a reciprocatory member mounted on the hollow member, an oscillatory member, pivotally supported on the reciprocatory member, having a finger to engage an o ening of the bar to feed the latter forward uring the movement of the reciprocatory member in one direction and to move outwardly away from the opening during the movement of said reciprocatory member in the other direction. to thereby engage the, next opening in the bar.
